The XF 35mm F1.4 R is a fast ‘normal’ prime for Fujifilm’s X system that behaves much like the classic 50mm lenses which used to be supplied with 35mm film SLRs. Optically it’s superb – impressively sharp at large apertures, with minimal distortion or chromatic aberration. Autofocus is quiet and reasonably fast, and like Fujifilm’s other ‘R’ lenses there’s an aperture ring on the lens barrel. If we were to buy just one lens for an X-system camera, this would be it.
